Specification of Letters Patent; Pajten ted-luay 13, 1919;

Application filed August 16, 1915. Serial No. 45,833.

To all whom it may concern 1 Be it known that I, HERMAN A. DE VRY, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Motion-Picture Machines, of which the fol lowing is a full, clear, and exact description. The invention relates to motion-picture machines.

Objects of the invention are to provide,

an improved. moving picture projector in which the feeding mechanism is constructed to operate on a loop of the film between two spools disposed side by side and adapted to receive the film edgewise to facilitate threading or placement of the film into the feed mechanism; an improved machine in which the rewinding mechanism is inclosed in a case with the feed mechanism and the supply and take-up spools; an improved machine in which the mechanisms are constructed so that a portion of the film may which provision is made for rewinding the film upon the supply spool without displacing either the supply-spool or take-up spool; to provide an improved machine which has the feed-mechanism, spools and rewinding mechanism contained within a single case and adapted for use with illuminating means in the samecase; and to provide an improved machine in which the supply and take-up spools are disposed side by side and in which the feed mechanism is organized to dispense with any rollersdisposed at an angle to the axes of the spools." Other objects of the invention will appear from the description of the machine.

The invention consists in the several noyel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

. In the drawings: Figure 1v is a side elevation of a machine embodying the invention, the cover forming one side of the'case bein swung into open position. Fig. 2 is a hOI'lzontal section taken on line 22 of Fig. 1 upon an enlarged scale. Fig. 3 isa vertical longitudinal section taken on line 3'3 of Fig. 2. Fig. 4 is a. front elevation of the spective of the framing device. Fig. 6 is a vertical section taken on line 6-6 of Fig. 3, showing the latch for the support for the roller which holds the film on the intermittent feed sprocket. Fig. 7 is a section showing-the latch for thesupport for the rollers for holding the film on the take-up sprocket. Fig. 8 is a perspective of said support. Fig. 9 is a section taken on line 9-9 of Fig. 1. Fig. 10 is a. horizontal section taken on line 1010 of Fig. l, the film being shown on the rewinding guide-drum. F 1g. 11 is a transverse section taken on line 11-11 of Fig. 2. Fig. 12 is a detail of the intermittent drive for the intermittent sprocket. Fig. 13 is a perspective of the case of the machine. Fig. 14 is a section through the fadjustable bearing for the intermittent feed-sprocket.

The film-supply and take-up 'spools,feedmechanism, rewinding mechanism and illuminating means for projecting light through the film are all inclosed within a case comprising a bottom 15, a front 16, a back 17, a top 18, a fixed side 19, and a cover 20 hinged to back 17 at 21 and forming one side of the case. The latter has a transverse partition 2-2 extending from the back to the front of the case to form a lower compartment therein which is adapted to contain the supply-spool 23, the take-up spool 24 and the rewinding guide-drum 25.

A vertical partition 26 extends between the partition 22 and the top 18 of the case to divide the upper 'portion thereof into a chamber 27 for the feed-mechanism and a chamber 28 for the illuminating means. The case is lined with asbestos, as at a, and

. partition 26 is formed of asbestos to render the case fireproof. The illuminatingmeans for projecting light through "the film com-' prises an electric lamp 29 mounted in a socket 30 which is supported on a bracket 31 .secured to the back of the case. This socket is electrically connected to a switch 32, the button 33 of which extends to the outside of the case. A tube 34 for the condensing lenses is mounted in partition 26 in back of the film and framing device. Lamp 29 is disposed in a box 35 which is separated from the walls of the case and partition 26 by anair space. An inlet 36 is formed in back 17 and an air outlet 37 is formed in the in the bottom of box 35 and an opening 39' is formed in the top of the box for ventllating the lamp. This illuminating apparatus forms the subject-matter of an application for Letters Patent being filed by me August 16, 1915, Ser. No. 45,632, so that more de tailed illustration and description thereof are not deemed necessary. This illuminating means serves to project light through the film, as it is advanced by the film-feed mechanism hereinafter described.

Spools 23 and 24 are coaxially mounted upon a spindle 41 which is secured by bracket 42 to the fixed side 19 of the case. A sleeve 46 extends through the hub of the take-up spool 24 and is provided with a feather or pin 47 (Fig. 10) for rotating said spool and a. pulley 47 whereby it is driven from the feed-mechanism. A sleeve 43 fixed to a rewinding pinion 44 and provided with a pin or feather 45 for turning the spool 23 is interposed between the hub of the spool and spindle 41. In operation; the sleeves 43 and 46 and the spools thereon, rotate in opposite directions, so that sleeve 46 will act as a drag upon the supply-spool during the operation of exposing the film. A spacer sleeve 48 fits loosely betweenthe spools. From the supply-spool, the film 50 passes between a pair of rollers 51 carried by the partition 22. These rollers are in' the same vertical plane or alined' and have their axes parallel to the axis of the supply-spool. The fihn in passing from the feed-mechanism to the take-up spool, passes between the rollers 51 alined with rollers 51 and carried by partition 22.

The several parts of the film-feeding mechanism are supported by a frame comprising a plate 54 which is secured by brackets 55 to the fixed side of the inclosi'ng case, a supplemental plate 56, suitably cross-connected to the plate 54, a back-plate 65 and a front plate 57: The feed-mechanism comprises a continuous feed-sprocket 59, an intermittent feed-sprocket and a continuous take-up sprocket 61. All of these sprockets are of the double type suitable for e a marginally perforated film. The axes of all of these sprockets are parallel to the axes of the supply and take-up spools. Sprocket 59 is in the plane of the supply spool and sprockets 60 and 61 are in the plane of the take-u spool. The framing device and guide for the film during exposure are alined with the intermittent-sprocke't 60 and the take-up spool. From sprocket 59, the film is looped and flexed laterally (Fig.1) so that it is free to guide itself without the use of rollers that are inclined relatively to the axes of the spools or feed sprockets. Thefilm-loop portion 58 passes to a guide-roller 63 which is mounted in lugs 64 on the back plate 65 of the feed mechanism frame.

Thence the film passes downwardly (Fig. 3)

between said' plate and resilient strips 66 hold the fillm against the back of said plate as it passes across the exposure-opening 67 in said plate. Thence the film passes under a guide-roller 68 mounted at the lower end of a slidable framing plate 69 andthence partially'around and over the intermittent feed-sprocket 60, thence to and under and partially around the take-up sprocket 61 from which it passes between rollers 51 to the take-up spool.

A tube 72 containing the projecting lenses 73 is slidably mounted in a fixed tube '74 in front of the opening 67 in the back plate 65. A rotating shutter 75 is secured to a shaft 76, to move across the front of the lens-tube. An opening 77 is formed in the front of the case, at the'front of the projecting lens-tube 72.

A main drive-shaft S0 is journaled in frame-plates 54 and 56 and is provided with a pin 81 adapted to fit into the notched end of the hollow hub of a crank 82 adapted to extend through an opening 83 in the cover of the case (Fig. 2). This crank is removable from shaft 80 so that the cover can be opened, and so that the crank may be placed in the case when the machine is being trans-' gear wheel 89 fixed ,'to said shaft, meshes with gear 87 on shaft 80, sothat sprockets 61 and 59 will be continuously driven while the main drive shaft 80 is being operated.

An oblique-toothed gear 90 (Figs. 2 and 3) is fixed to sprocket-shaft 88 and meshes with a correspondingly toothed pinion 91 .which is fixed to the shutter-shaft 76. This shaft imparts movementlto the shutter and is also extended rearwa'rdly and provided with an oblique toothed-pinion 92 to impart movement to the intermittent feed-sprocket 60. Gear 92 meshes with an oblique toothed gear 93 on a short shaft 94- (Fig. 12). A notched disk 95 and a pin 96 on the hub 97 of a fly wheel 98 serves to alternately drive and look a star-Wheel 98 fixed to the shaft 99 of the intermittent .feed sprocket 60. This mechanism exemplifies gearing whereby the intermittent feed sprocket 1s driven through the shutter-shaft and in which the latter is utilized for transmitting motion to the intermittent feed mechanism.

A pair of flanged idler rolls 100, 101 (Figs.

tinuous feed sprocket 59 are mounted on threading or removing the film, it is only necessary to press back the latch 104 and swing arm 102 forwardly, whereupon the idlers and the sprocket will be separated for edgewise insertion or removal of the film. These and all the idler rolls co5perating with the feed-sprockets are grooved opposite the teeth of the sprockets to permit the teeth to pass through the marginal perforations in 'the film. The outer end of sprocket 59 and the idler rolls 100 and 101 are free to permit the film to be inserted laterally between the sprocket and the idlers. Sprocket 59 is on an outwardly projecting portion of shaft 88 and this manner of supporting it permits a loop of the film to be placed on said sprocket. The film passes under take-up sprocket 61 so that the film loop may,.by edgewise movement, be placed on or removed from said sprocket.

An idler roll 106 (Fig. 3) is adapted to hold the film on the intermittent feedsprocket'60. This roller is mounted on 9. lug on a slidable bar 107 which is slidably mounted on the inner side of frame-plate 54 by screws 108 and slots 109. A stirrup 110 (Figs. 3 and 6) is fixed to the lower end of bar 107 and a spring-latch 111 secured to the outer face of plate 54, is adaptedto lock bar 107 in position to hold roller 106 in operative relation to the intermittent feedsprocket 60. To release bar 107 so that it can be lowered to move roller 106 away from sprocket 60, it is only necemary to insert a finger through the stirrup 110 and push the latch 111 laterally "to release the bar, and then with the same finger exert a downward pressure upon stirrup 110. Sprocket 60 and roller 106 are also supported at one end only, so that one end thereof will be free to permit the film to be inserted edgewise between them. This device for locking the support for the roller 106 can be easily and quickly operated for convenience in inserting and removing the film. Upward movement of the bar will cause it to be automatically locked to hold the roller in operative relation to the film.

A pair of flanged rollers 114 and 115 are provided for holding the film on the takeup sprocket 61. These rollers are mounted on studs 116 projecting laterally from an arm 117 of a bar 118 which is slidably mounted on the inner face of frame-plate 54 by screws 119 and slots 120. A stirrup 121 (Figs. 3 and 7) is fixed to the lower end of bar 118 and a spring-latch 122 secured to one face of plate 54 is adapted to. hold the bar 118 and the rollers carried thereby in raised position. The fingeriece 123 at the lower end of latch 122 is isposed in the stirrup 121, so that the insertion of a finger in the stirrup will release the latch so that the bar can be lowered by downward pressure upon the stirrup. The latch will autoinatically lock the bar when the latter is raised. This device exemplifies simple means for unlocking idler rolls 114 and 115 to facilitate edgewise insertion and removal of the film. It will be observed that these idler rolls 114 and 115 are also supported at one end to leave the other end free for the lateral insertion and removal of the film.

The framing slide 69 (Fig. 5) is slidably mounted on the front face of the back-plate 65, by screws 125 and slots 126. Roller 68 is mounted in lugs 127 depending fromlslide 69. A lever 129, fulcrumed at 130 (Fig. 3), has its rear end forked to engage a pin 131" secured in forwardly extending lugs 132 on slide 69. The latter is formed with an opening 133 so that the exposure opening 67 will not be obstructed. A rod 131 is pivoted to the front end of lever 129 and extends varying the loop of the film between the intermittent feed-sprocket which holds the film and that portion of the film which is held against the back of plate 65.

Spring pressure strips 66 (Figs. 2 and 3) are secured to a gate 134 which is hinged by a rod 135 held in lugs 136 on the fixed frameplate 65. This gate 134 is hinged to per- -mit the edgewise insertion of the film-loop between plate 65'and the pressure strips 66 (Fig. 2). A latch 137 (Fig. 1) is adapted to hold the hinged plate in operative position. To insert or remove the filmbetween plate 65 and spring 66 and to extend the film around guide-roller 68 on the framing slide and the guide-roller 63 at the upper end of plate 65, it is only necessary to release the hinged plate 134 and swing it backwardly and inwardly.

The feeding and guiding mechanism described exemplify a machine in which the continuous and intermittent feed devices act upon a single loop of the film between the supply and take up spools and in which the different portions of this loop may be placed on these devices and across the plate having the exposure-opening therein, by edgewise insertion, sothat the necessity of threading an end through any portion of the mechanism is avoided. It will also be observed that there is no twist in this loop. Both reaches of the loop can be slipped edgewise into or out of the guide-rollers 51, 51 in partition 22 to facilitate a rewinding of the filin at any point, and for this purpose the slot between said rollers in-said partition is extended to the open side of the case.

A gear-wheel 142i is di d at the sleeve 143 for said hub.

which is adapted to receive the slotted inner end of thehub of crank 82. To rewind the film, after it has been looped around drum 25, hub 82 of crank 83'into 'theub of gear 142-and then it is only necessa to insert the turn the crank, which impart movement to 'fthe supplyespool 23 through pinion 44, sleeve 43 and pin45." The spring belt 86 act asadrag upon the take-up spool 24 during the rewinding operation. This construction exemplifies one in which'the crank for o rto operate inclosed rewinding mechanism, and in which rewmdlng mechanlsm 1s disatinginclosed film feed mechanism is utilized posed in the I automatically operating fire-shutter 150. is adapted to-drop over the ight-op'emng in'gate 134, bein secured at itsupper-endto area 151 which is pivotedinlugsf152on said gate. Rod 151 has a crank 153' (Fig. 11 )fat its inner end which is connected by a llnk.

154 to an arm on a disk 155, which is frictionally held a ainstone side of pulley 85 on the main sha '80 by a light spring 156.

Sprin 156 is applied to normally hold and-,

osition to hold door 150 isk 155 in closed. Link 154 as a slot 157 for pin 158 on disk 155 so that the door will not .be opened until shaft 80 is being operated at 'sufiicient speed to cause the friction between ulley 85' and disk 155 to operate the link and liold the door 150 raised against the force of spring 156. This device exemplifies simple means for. automatically operatmgthe fireshutter when the machine is in motion.

A split clamping ring 160 (Figs. 3 and 4) is secured on .the front end of the lens-tube,

72 being secured thereon by a screw 161. A screw-threaded ear 162 is formed on thls rm and an adjusting screw 163 dpasses throug said ear, has itsmner reduce end journaled in front plate 57, is held a'gainst'longrtudmal movement in the front wall 16 of the case and is provided with a thumb-wheel 164 at its outer end whereby the sleeve may be nale'd' in a trically by ii uts 175 and 176 adapted to the front plate 57 of the n frame and in an inturned'lug 54" of' frame-plate 54.

When .this has been done, the ate 134 will be latched in position to cause t e pressure strips 66toengage the film and frictionallv hold it against plate 65, roller 106 will be mo nted in frame-plate 54 and aclamp the so eed-mechaad usted in operative relation to sprocket I 60,'rollers 114, .115 will be locked in operative position with respect to sprocket 61 and rollers 100 and 101 will be locked in operative relation tosprocket 59. The cover of the case will then be closed and by ap lying the operatillilg crank 82'to shaft 80 an turninglthe era the machine will be operated v 100 the film will be-ilnwound' to intermittently advance the film across the exposure-opening and to take up the exposed portion of the film.

If, in the course of exposing a film, it should be desired to rexpose a portion thereof or' to discontinue the projection of the ictures thereon before all of the fihn has een-exposed, it is only necessary to release the idler-rolls and unlock gate 134, whereupon, the entire film-loop can be withdrawn laterally from the feed-mechanism and from the partition 22 and looped around the rewinding drum 25. The crank 82 can then be connected to the rewinding gear 142 whereupon the supply-spool 23 will be operated to wind the film off the take-up spool 24.

The invention thus exemplifies a moving picture projector in which the supply and take-up spools, film-feeding mechanism and rewinding mechanism are all inclosed. within a single case for convenience in transportation and operation. The machine is organized so that the feed-mechanism will act upon an untwisted loop between the supply .construction that it can be formed of stampings or by dies. The invention is not to be understood a restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
